This is a tough decision. I have not yet been to Narcoosess, but the other restaurants i have eaten at several times. These 3 are all very kid friendly. Here is my take on each of them.
California Grill: so many items on the menu I want to try, so little time. Food is top notch and so is the service. we did have a bad server once in like 10 visits, so pretty good there. The view is awesome, even without the fireworks-the observation deck is cool too-bird's eye view of MK and most of the World. It tends to be loud because it is one large open area with an open kitchen. There is a bar in the middle of the restaurant, which contribrutes for most of the noise. I personally love the atmosphere. It is bright inside and they dim the lights for the fireworks. My favorite dish is the pork tenderloin with goat cheese polenta and anything chocolate for dessert. The food is of course fresh Californian cuisine, lots of seafood items and new American style
Artist Point: food and service are also top notch here. The menu offers more Pacific Northwestern flared items-salmon, game meats and beef. The food is more like upscale comfort food-pork chops, smokey mushroom soup & big pieces of meat. I love the buffalo sirloin with onion marmelade, beet salad, venison rolls, the woodplank salmon and the cobbler, which is the one non chocolate dessert I love. Lots of dark wood tables, vaulted ceiling that makes the dining area feel huge, and the lighting is enjoyable as well. This restuarant is not as loud to me as CG, it is a little more calm because there is no bar here. Artist Point offers a view of the resort pool.
Citricos- is a large open room with an open kitchen. It has a lovely view of the quiet pool and grounds of the GF. The noise level is higher than AP, but definetely lower than CG. Not many people eat at the bar here-in fact I do not know if you can eat there. The service has always been wonderful-the staff is great here. The food is influence by Mediterranean cuisine-flavors from Italy, Greece, Northern Africa and southern Spain. There are several fish entrees as well as some seafood appetizers. The filet Sicilian with crushed 4 cheese potatoes is delicious. I have also had the bass with rissoto, veal shank, gateau of crab, arancini, goat cheese salad, and hearts of palm salad. All were spot on and the desserts are great too. This is probably our favorite place.
Well I do not know if I helped or confused you more. you can always ask more questions

. Have fun.
